## Data notes
AidData's Research Release 2.1 is a snapshot of the AidData's entire project-level database from  January 2013. This database includes 1.2 million aid activities funded by more than 80 donors from the 1940s to present. AidData Research Releases are particularly useful for researchers because they are static versions of the data that allow for replication and comparison. AidData�s goal is to publish updated research releases on an annual basis (or more frequently if appropriate). For detailed information about this data set, see the AidData User's Guide.
